SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 732,646, dated J' une 30, 1903.

Application filed April 13, 1903. Serial No. 152,413. (No model.) A

To all whom it may concern.-

Be it known that I, PETER JOHNSON LUN- DEN, a citizen of the United States, residing at Brookings, in the county of Brookings and State of South Dakota, have invented certain new and useful Improvements in Snow-Plows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apperta-ins to make and use the same.

This invention relates to snow-plows of the character adapted to be attached to the front of a locomotive or motor-car and to be propelled forward thereby to remove the snow from the trackway. Y

The object of the invention is to provide a plow of this character which is efficient, durable, and inexpensive, adapted alike for electric and steam railway work and designed to allow the snow toV be taken up and dumped at the sides of the trackway at desired intervals, and which, furthermore, may be operated by suitable mechanism actuated by the motive power of lthe locomotive or motor-car.

With these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure lis a perspective view of asnow-plow embodying my invention. Fig. 2 isa bottom plan view of the same. Fig. 3 is a vertical longitudinal section. Figs. 4 and 5 are vertical transverse sections on the lines 44 and 5 5 of Fig. 3.

In carrying my inventioninto practice I provide a truck-frame or supporting-framework l of suitable form and construction and mount the same upon wheels 2 to provide a car which may be propelled by a locomotive or motor-car along the trackway to be cleaned from snow. This truck-frame is provided at its forward end with a scoop or shovel 3 to take up the snow as the device is propelled along, and the rear of the same is formed with a platform longitudinally divided to provide tilting sections 4 and 5, which are hinged or pivoted at their outer edges to the framework and are adapted to tilt in reverse directions to discharge the snow upon opposite sides of the trackway. Rising from the frameworkimmediately in rear of the plow or shovel is a vertical divider 6, which breaks up the snow passing from the shovel onto the platform and at the same time divides it, so

as to cause a like amount to be conveyed as the car moves along to the two tilting sections. Y

The platform-sections are actuated through the medium of a longitudinal rod 7, disposed beneath the framework, which rod is connected to a pair of bell-crank levers -8, located i their pivotal connection with the links 12 to receive a lug orl depending portion on the bracket-plate 14, 'secured one to each ofthe said tilting platform-sections 4and5. By this construction it will be seen that when the rod 7 is moved rearwardly the crank-arm 9 will be drawn upon to elevate the arms 11 and to thereby leave the free sides of the platform-sections totilt the same to an inclined position, so that the snow will discharge therefrom to opposite sides of the trackway. The connection between the link 13 and bracket 14 allows the sections 4 and 5 to tilt freely without strain on the bell-crank lever or pivot l2. Y

In practice the rod 7 may be operated by compressed air, electromechanical devices, steam, or mechanical connections of any preferred kind actuated by the motor mechanism of the locomotive or motor-car used to propel the plow.

VAt the rear portion ofthe plow o r scoop v3 is a tilting guard or fender 15, which normally lies flush with the bottom surfaceof-{the plow and is adapted to be tilted vertically against the divider to serve as a stop to prevent the snow onthe platform from sliding forward when the plow is brought to a quick stop or is being backed away from a snow-drift.

IOO

This

guard is automatically operated when the plow is brought to a stop or backed by means of an actuating-rod 16, disposed upon the under side of the truck-frame and connected at its forward end to one arm of a central pivoted lever 17, the other arm of which is jointed by a link 1S to a bracket 19 on the guard. The rear end of the rod 16 has an eye 20, by means of which it may be connected to the coupling-` pin of the propelling-locomotive or motor-car, so that when said car stops suddenly or backs the play between the connecting-couplings will cause the rod 16 to be drawn upon to operate the guard, `thus preventing the snow from shifting forwardly.

In the operation of the device the snow-plow is attached to the front end of the locomotive or motor-car and propelled forwardly, and the scoop or shovel 3 takes up the snow, which by the forward motion of the car is caused to pass upon the tilting platform, the seats of which are raised at determined intervals or desired periods to effect the discharge of the snow. When the locomotive or motor-car is brought to a stop or is backed on encountering a drift too heavy for the plow to go through under normal speed, the snow is prevented from shifting forward and clogging the scoop by the guard, which is actuated in the manner previously described. By the use of the divider 6 the snow is prevented from accu mulating in lumps and passing unequally between two platform-sections, so that both sections will receive substantially the same amount of snow, thus enabling them to be operated easily and without binding.

The device is efficient in action and may be used for either street or steam railway work.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the inven tion will be readilyunderstood without requiring a more extended explanation.

Various changes in thegform, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having thus particularly described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a snow-plow, the combination with a supporting-frame provided at its forward end with a shovel or scoop, of a platform composed of tilting sections, means for tilting said sections, and a divider at the forward end of the platform and between the sections, substantially as described.

2. In a snow-plow, the combination with a supporting-frame provided with a scoop, of a platform, means for removing the snow therefrom, and a guard at the forward end of the platform operable to prevent the snow thereon from shifting forward when the plow is brought to a state of rest or backed, substantially as set forth. v

3. In a snow-plow, the combination with a supportingframe provided with a plow or shovel, of a platform composed of tilting sections, means for tilting said sections, a guard at the forward portion of the platform, and means for elevating said guard to prevent forward shifting of the snow, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
